I'm pretty small (5'4", pre-pregnancy weight 117 lbs). At 17 weeks, I'm at 124 lbs, and I wanted something that didn't cut across the middle of my belly. I was nervous about anything "one size fits all" - that's a tall order for regular women's wear, but add pregnancy, and that didn't seem possible. However, I'm happy to report that these fit great- they don't have a ton of compression (unsurprising, as I'm on the small end of what they are supposed to fit), but they were snug. Very lightweight and silky, perfect for summer. The top came nearly up to my braline. These clearly have plenty of room to grow. and love the nude/black color palette, that works with everything. Love these, very happy and sure these will be my undergarment for the rest of pregnancy.
